This year might be even later opening and thus spoiling it for most of the peak run in Lower Fraser....all because you can catch a bloody sockeye on a pink spoon in tidal Fraser, rrrright - Thanks DFO!
For what it's worth, the test fisheries over the last 4 or 5 cycles show the bulk of the pink runs are in the Fraser from roughly around Sept 5-20 and my own experiences would concur, though never really tried after the 25th. A slightly delayed opening should still let you catch a good portion of the run.
As for sockeye by-catch in the Tidal Fraser, yes it's basically impossible while targeting pinks, though the subtleties between that and flossing in the non-tidal appears mostly irrelevant the DFO. Especially since there is already a conveniently defined Tidal/Non-Tidal boundary (Mission Bridge) below which 'non-selective' methods are basically ineffective, once the pink numbers reach a point of confidence in reaching escapement goals, then it seems reasonable to open at least the Tidal portion, if impact on sockeye is still a concern.
